(2) A B S T R A C T In this study the author tried to chose a multiple approach to lovesickness, based on biological theories with emphasis on ethological concepts of research. Hypothesis about the experience, course and functionality of lovesickness covered cognitive, emotional and behavioural aspects. The relation of various mate choice parameters to the perception of lovesickness has been discussed in a sociobiological framework. Concerning ethological aspects of lovesickness the author could show a relation between emotional status after separation and ’quality‘ of performed behaviour (motion), using a ‘non semantic approach’ to behavioural analysis. The author discussed the possible functionality of lovesickness in a framework of communicational and evolutionary theory and proposed that lovesickness could have an adaptive value. Last but not least the author introduced BHS, the ’Broken Heart Syndrome‘ covering lovesickness and its related properties.

Theoretical considerations 4.1.1 A short history of ‘love and sex research’. For a very long time the term ‘love’ was only associated with a deep emotional feeling. Love and all accompanying things were seen as ‘untouchable’ things with a mystic flavour, and were praised in all manner of art forms through the ages. Love is still one of the most popular themes in pop music and literature. Scientists, however, discovered ‘love’ as an interesting topic of research far more recently. In the late 1940s and the beginning 1950s, the studies of Alfred Kinsey and his associates on male and female sexual behaviour (KINSEY et al. 1948, 1953) initiated a boom in scientific research on human sexuality. In the mid 1960s, William Masters and Virginia Johnson continued this research with studies on ‘human sexual response’ (MASTERS AND JOHNSON 1966). Irenäus Eibl-Eibesfeld published his book Love and Hate, an ethological study of reverse emotions (EIBL-EIBESFELD 1970); in 1970, Zuck Rubin published his groundbreaking study Measurement of romantic love, establishing love as a serious topic of scientific inquiry (RUBIN 1970). In the late 1970s, Donald Symons wrote his book The evolution of human sexuality’ (SYMONS 1979), which pointed ‘love and sex research’ in a new direction by focusing on anthropological and evolutionary questions. In the 1980s, much research was done about ‘behaviour and strategies of human mating’, with a new emphasis on sociobiological theories of human sexuality (e.g. BUSS & BARNES 1986, BUSS 1989). In the late 1980s, a new boom of ethological studies about ‘human mating behaviour’ and ‘flirting’ was initiated which still continues (e.g. GRAMMER 1989 and 1990, KRUCK 1989). Throughout the 1990s, questions concerning cross-cultural perspectives on love and sex have been the focus of discussion (JANKOWIAK & FISHER 1992, JANKOWIAK 1995, HATFIELD & RAPSON 1996). In addition, several book-length reviews of current research have been published: Susan and Clyde Hendrick, for example, wrote an overview Romantic love (HENDRICK & HENDRICK 1992). Elaine Hatfield and Richard Rapson compiled information about in their Love, sex and intimacy in psychology, biology and history (HATFIELD & RAPSON 1993). At the same time, Karl Grammer published his book Signale der Liebe about the biological constraints of love which showed the strong influence of ethological research (GRAMMER 1993). 4.1.2 Lovesickness – a taboo in scientific research? However, most of ‘love and sex research’ through all the ages has mainly focused on the positive aspects of love; the negative aspects and problems co-occurring with love as a topic of research have been largely neglected (DUCK 1994). Most studies conducted dealt with divorce, while studies about the break up of ‘romantic relationships or love affairs’ (partners are not married) are still rare (e.g. HILL et al. 1979). The phenomenon called ‘lovesickness’, or a ‘broken heart’, however, has remained almost completely neglected. If one opens an issue of any society magazine or tabloid paper, several stories about ‘lovesickness’ or ‘breaking hearts’ can be found. Such journalistic accounts mostly contain personal statements of ‘victims’ and how they overcame their crises. In contrast, only a few scientific studies deal with the subject to a greater or lesser extent. -5- 4.1.3 What do we know about lovesickness? In 1979 Dorothy Tennov published a book entitled Love and Limerence – the experience of being in love (TENNOV 1979). She based her book on interviews with students. Limerence describes the circumstances of falling or being in love and is comparable to the concept of ‘passionate love’ (HATFIELD & RAPSON 1993, p. 33 ff.). In contrast to previous works, Tennov’s book focused more on a person’s emotional and cognitive experiences of another person than on the actual relationship itself. These experiences are in turn characterised by physiological reactions, intensive thinking about the other, rapidly changing moods, fear of rejection, etc. Limerence resides mainly in ideas and fantasies about another person, the ‘limerent object’. This concept is closely related to what is known as infatuation (passion without intimacy or commitment, STERNBERG 1988, p.122). A second, highly speculative book, The chemistry of love, was written by Psychiatrist Michael Liebowitz in the early 1980s (LIEBOWITZ 1983). In it, Liebowitz argues that passionate feelings are comparable to an amphetamine high and that Phenylethylamin (PEA), an amphetamine like substance in the human brain, may be related to feelings of romantic love. Thus the crash that comes after the break-up of a relationship may be similar to amphetamine withdrawal. Drug addicts and ‘love addicts’ seem to have something in common (LIEBOWITZ 1983, FORMAN 1987). Lovesickness in this sense is considered to be an epiphenomenon of the separation process. Liebowitz also offers a very interesting remark on emotional difficulties that do not fit traditional diagnostics. He discusses a subtype of depression – ‘hysteroid dysphoric’ – that had first been introduced by Donald Klein. These people continually fall in and out of love. When in love, people are euphoric, full of energy; they worship their partners and they are very sociable. When the relationships end, they suffer a complete break down, and behave in the opposite way: they feel awful, overeat, sleep too long and avoid social contacts. The ‘hysteroid’ period is very similar to an amphetamine high, whereas the ‘dysphoric’ period parallels a withdrawal from amphetamine. These people, Klein suggested, were individuals whose crucial problem was their immense sensitivity to rejection (LIEBOWITZ 1983, p.166). Roy Baumeister’s and Sara Wotman’s controversial book Breaking Hearts explores ‘unrequited love’ from both perspectives – that of the rejected and that of the rejecter (BAUMEISTER & WOTMAN 1992). Their worked was based on stories written by college students. The authors asked the students to write two stories of unrequited love, one about a personal experience in the role of the rejected and another in the role of the rejecter. Surprisingly, they conclude that the rejecters suffer more. They feel guilty at first, but later on they feel trapped and sometimes even persecuted. More recently two studies about ‘real lovesickness’ have been published: A psychoanalytically-oriented one written by Gertrude Gahleitner-Senger (GAHLEITNER-SENGER 1992) and a psychological study by Wilma Mert (MERT 1995). Gahleitner-Senger conducted an interview-based, psychoanalytic study about the role of ‘transitional objects’ after the break up of a relationship. The formation of a ‘transitional object’ in a critical life event strengthens the structure of the self. The theoretical assumptions underlying her views on the transition process from the ‘old -6- identity’ to a ‘new identity’ are based on Bowlby’s theory of attachment and loss (see later on). Gahleitner-Senger discovered five phases of transition (see table 1). Table 1: Phases of transition in lovesickness according to Gahleitner-Senger 1992. phase description 1. 2. 3. 4. Threatening Numbness Negotiating Regression 5. Acceptance Instability of the old identity Internal breakdown Trying to keep in touch with the (ex)partner External breakdown, transition object formation Establishing a new identity As regards ‘lovesickness’, the self regresses to a developmental stage where it received deep satisfaction. During the regression the self should have the ability to reorganise. Senger describes four different types of formation of a ‘transition object’ (see table 2). Table 2: Types of transition objects according to Gahleitner-Senger 1992. object description 1. 2. 3. Oral factor Addiction factor Sex factor 4. Substitution factor Increased ingestion Increased inclination to nicotine, alcohol and drugs Increased sexuality to satisfy the desire for intimacy and presence Increased social contacts, activities and hobbies The ability of the person abandoned to establish a ‘transition object’ of any type shortens the period of mourning. Consequently, people with lovesickness seem to behave, feel and show symptoms like people who suffer from grief. According to Senger, lovesickness would function to re-establish a stable self. Mert performed an interview study in which she focused on different strategies for coping with lovesickness and its related stress. For coping with stress she found differences between the sexes; men rather engage in ‘cocooning’: they accept their fate and allow the situation to ‘fade away’, whereas women bridge the situation with increased active social contacts, they seek social support. In addition, Mert shows that the self-image undergoes certain ambiguous changes (e.g. increased selfconfidence, increased fear of coming relationships), which in some cases remain (MERT 1995). -7- 4.1.4 A taxonomy of lovesickness. After browsing different papers and books dealing with ‘lovesickness’, the reader remains with an uncertain feeling of how to define ‘lovesickness’. In the literature four types of lovesickness are discussed (see table 3). Table 3: Different types of lovesickness. type description LTI Lovesickness type I LTII Lovesickness type II LTIII Lovesickness type III LTIV Lovesickness type IV Refers to a past relationship - the broken heart, a negative experience. Refers to a not yet established relationship, or to a not re-established relationship - unrequited love, limerence, a negative experience. Refers to an intensely passionate style of love - being ‘nuts on love’, a positive experience. Refers to a continually switching between falling in love and falling out of love - ‘hysteroid dysphoria’, an ambiguous experience. This study will deal only with ‘Lovesickness type I’, the broken heart phenomenon. Further the only plausible and consistent definition of lovesickness so far can be found in Gahleitner-Senger 1992: Liebeskummer ist ein, mit intensiven psychischen und physiologischen Reaktionen verbundener Zustand einer Person, deren Streben nach seelischkörperlicher Vereinigung vom Liebesobjekt zurückgewiesen wird und im Falle des endgültigen Verlustes des Liebesobjektes mit einem Prozeß des Trauern einhergeht. Gelingt die Trauerarbeit nicht, besteht die Gefahr einer Fixierung auf die depressive Verstimmtheit, sowie des Verlustes der Liebes-, Kontaktund Arbeitsfähigkeit. Gahlteitner-Senger 1992, p.99 4.1.5 The anthropology of lovesickness It seems to be commonly accepted that lovesickness is the reverse side of the the coin of the emotion called love. Separation, rejection, obsession and grief are the costs of (romantic) love. In preparing the references for this study, the author performed a search in various ethnographic data bases. Casting a quick glance at the literature on the motive of lovesickness (all three types), one notices that scattered but recurrent cross-cultural stories about lovesickness seem to exist. Search results suggest that various forms of lovesickness have been reported over the ages, among all kinds of ethnic groups. The data also show that often suicide was the only ‘solution’ to overcome disappointed love. More recently, Jankowiak reported in his book Romantic Passion about the existence of India’s Society for the Study of Broken Hearts, which was founded in 1992. He writes that the -83rd of May is national Broken Hearts Day, [which is] for the romantically disappointed and the love rejected to commiserate with one another. Jankowiak 1995, p.5 Jankowiak’s book concludes that ‘romantic love’ is a human universal. The more significant question in the current context would be whether or not lovesickness is a universal experience as well. Jankowiak again: Perhaps a stronger argument for romantic love’s universality can be found in the widespread cross-cultural fear of rejection and love’s loss. Jankowiak 1995, p.5 Lovesickness should also be an human universal, and therefore worthy of further scientific interest. 4.1.6 Psychological precursors of lovesickness. There is no consistent theory about the psychological mechanisms of lovesickness. Even in the understanding of a phenomenon like divorce, solutions derive from known concepts like ‘attachment’, ‘detachment’, ‘bereavement’, ‘grief’ and ‘mourning’. All these terms are associated with the experience of any form of ‘loss’, which seems to be a good starting point for understanding lovesickness as well. Most theories in this field can be related to the work of Bowlby, Ainsworth, Harry and Margaret Harlow and Suomi & Zimmerman. 4.1.6.1 Attachment Bowlby (BOWLBY 1969, 1973, 1980) studied the process of attachment, separation and loss in children. He formulated in his attachment theory that normal attachment is crucial to healthy development. Appropriate attachments in infancy play an important role in a person’s ability to form stable relationships later in life. Attachment develops gradually and is facilitated by interaction between the mother and the infant. On the basis of Darwinian, evolutionary theory, Bowlby suggested that attachment behaviour ensures that adults protect their infants. Thus the process of attachment not only occurs in every human social group but also in other organismic groups. Ethological studies show that subhuman primates and many other animals perform attachment behaviour patterns that are presumed to be instinctual and ruled by inborn tendencies. A referring system is seen in imprinting, where attachment happens during a short (some hours), so called sensitive or critical period. A similar period has been postulated for human infants, although its presence is highly controversial. However this critical period occurs over a span of years, rather than hours. According to Bowlby attachment develops in four phases (see table 4). -9- Table 4: Bowlby’s 4 phase process of attachment. phase age description 1 Preattachment stage birth to 8 or 12 weeks 2 Attachment-in-themaking Clear-cut attachment 8 to 12 weeks to 6 months 6 months thorough 24 months Independence of mother figure 25 months and beyond The new-born orients towards its mother, follows her with its eyes and moves rhythmically with her voice. The infant becomes attached to one or more persons. The infants cries and shows other signs of distress when separated from the caretaker (mother). On being returned to the mother the infant stops crying and clings. The infant distinguishes between it self and the mother figure and a more complex relationship between the mother and the child can develop. 3 4 Ainsworth (AINSWORTH 1978, 1979) expanded on Bowlby’s observations and concentrated on the interaction between the mother and her baby. She discovered that the ‘quality’ of these interactions influences the baby’s current and future behaviour. Sensitive responsiveness to infant signals (e.g. cuddling when the baby is crying), causes infants to cry less later on. Close bodily contact on demand is associated with the growth of self-reliance. Unresponsive mothers produce anxious and emotionally immature babies. Ainsworth verified that attachment reduces anxiety. The formation of a ‘secure base’ via attachment enables the child to leave the attachment figure and explore the environment. The Harlows (HARLOW & HARLOW 1965), Zimmerman (HARLOW & ZIMMERMAN 1959) and Suomi (SUOMI & HARLOW 1975) studied the development of love in monkeys and they discovered that contact comfort for (monkey) infants is far more important than previously considered. They demonstrated the effects in monkeys when they were kept from forming attachments at all. The isolates were withdrawn, unable to relate to peers, unable to mate, and incapable of caring for their offspring. More recently, theories have also focused on neurobiological and endocrinological processes leading to ‘psychobiological theories’ of ‘attachment and loss’ (BENTON 1990, GILBERT 1989, INSEL 1991 and 1992, RICHARD et al. 1991, KRAEMER 1992, PANKSEPP 1992). 4.1.6.2 Separation anxiety Depending on a child’s developmental stage and phase of attachment, a short episode of separation from its caretaker (mother) produce intense anxiety. It is a ‘normal’ reaction and most common at 10 to 18 months of age and disappears by the end of the third year. 4.1.6.3 Behavioural response to a longer period of separation Bowlby again described a predictable pattern of behaviour performed by children who are separated from their mothers for long periods of time (at least three months); see table 5. - 10 - Table 5: Bowlby’s phases of separation and corresponding patterns of behaviour. phase description 1 Protest 2 Despair 3 Detachment The child shows protest against the event of separation by crying, calling and seeking for the lost object. The child lose hope that the mother will ever return. The child emotionally separates itself from the mother. These phase is accompanied by ambiguous feelings – at the same time the child wants its mother and is angry at her for the abandonment. 4.1.6.4 Grief, mourning and bereavement All three terms address behavioural patterns of persons who endured a critical loss. ‘Grief’ is a complex emotions associated with the death of a beloved person. In colloquial speech grief is used synonymously with ‘mourning’, although mourning in the strict sense is the reaction by which grief is resolved. ‘Bereavement’ describes the state of being abandoned of someone by death and the state of mourning. All three terms show a great overlap in its emotional, somatic, cognitive, motivational and behavioural manifestations. Grief in general can occur after a variety of different losses. They can include the loss of a job, loss of status, loss of a beloved person and of course the loss of a intimate relationship. As described by Bowlby (BOWLBY 1961), and later on by Parkes (PARKES 1965, 1969, 1971, PARKES & WEISS 1983) grief follows a more or less stable pattern with different phases (see table 6). Table 6: Comparison between Bowlby’s and Parkes’ concept of the grief process. Bowlby phases 1 2 3 4 5 Parkes Numbness Yearning, Searching Disorganisation, Despair Reorganisation - Alarm Numbness Pining (searching) Depression Recovery, Reorganisation 4.1.7 A more pragmatic ethological approach to lovesickness. 4.1.7.1 Human mating strategies and attachment. On the one hand the ‘quality’ of early attachment is crucial to the ability to form stable relationships at all and the ability to deal with any forms of loss (see also MIKULINCER & EREV 1991). On the other hand stable relationships, from a biological point of view, are crucial to reproductive success of both sexes. - 11 - However, the function of courtship is optimising reproductive success of the individuals involved. Sexual selection is driven by asymmetrical parental investment in their offspring. So females and males should follow different mating strategies (TRIVERS 1972). In humans and other mammals costs to females are higher than to males, because fertilisation occurs internally within females as gestation does. Females can reduce their mating costs by male assistance and on the other hand they can optimise their reproductive success by being more choosy and inducing sperm competition in males (BAKER & BELLIS 1995). They should show greater interest in maintaining a stable relationship with a male and try to force them to invest in their offspring. Therefore females should prefer males who are able to provide resources related to parental investment, such as food, refuge, territory and protection. Among humans resources are typically translated into economic status. This suggests that females will chose males with higher status, signalling their potential access to various resources. Female choice and asymmetrical parental investment leads to intrasexual competition among males through sexual advertisement (MAYNARD SMITH 1974, TRIVERS 1972). Reproduction for males is limited by access to reproductively valuable or fertile mates. Because fertility and reproductive value are linked in females males will value relative youth and physical attractiveness in potential mates (SYMONS 1979). In contrast to the females males cannot insure that their investment is directed toward their own offspring and not the offspring of another male. So sexual jealousy in males is one mechanism which works against possible female philandering, preventing male cuckoldry (DALY et al. 1982). An alternative strategy to increase reproductive success of the male would be practising philandering, too. In sum a woman’s ‘mate value’ should be determined more by their reproductive capacity. So physical appearance and youth should be more highly valued by men. A man’s ‘mate quality’ would be more determined by the ability to provide resources and therefore more highly valued by women. These predicted sex differences in human mate preferences were tested and could be verified in 37 cultures by Buss. In all discovered cultures the ability to form stable relationships ranked first in both sexes. As predicted men preferred female attractiveness rather then female status and women favoured male status rather than male attractiveness (BUSS 1989, 1994). The quality of a relationship seems to be determined by the proverb ‘birds of feather flock together’. The more mates resemble the longer the relationship will last and the more stable it will be. This form of mate choice is called ‘positive assortative mating strategy’. Mates are similar in origin, physical appearance, age, religion, social status and personality traits (see multiple references in GRAMMER 1993, p.378408; HENSS 1992). Overall love’s proximate function is to ensure closeness between the mates and thus the ability to control each other (GRAMMER 1993). 4.1.7.2 Consequences of detachment and loss. Thus if a relationship breaks up, and if positive assortative mating happens, the perceived severity should be affected by the amount of intimacy and similarity between the mates. An other modulating factor for the severity of the perceived loss, or even the decision leaving the relationship at all, could be ‘mate value’ itself. To test - 12 - this assumptions a rating study of subjects’ faces was performed (details see methods 6.2). Going even further and following the concept of the ‘unity of the human psyche’ any form of loss, e.g. of a relationship, will cause distress on all systems’ levels of the human psyche (see details in section 4.2 ff.). Therefore responses to stressful life events expresses throughout the psychological, physiological and behavioural level. A large number of studies have explored the physiological processes underlying various forms of mood disorders, including depression, anxiety states, disorders of maternal and peer group affiliative behaviour, detachment, separation and even suicide. The data reported are most consistent with the fact that mood disorders are associated with heterogeneous dysregulations of the biogenic amines. Abnormal levels of their metabolites – such as 5-hydroxyindoleacetic acid (5-HIAA), homovanillic acid (HVA), and 3-methoxy-4hydroxyphenylglycol (MHPG) – in blood, urine, and cerebrospinal fluid (CSF) could be discovered. Neurotransmitters included in this processes are norepinephrine (NE), serotonine (5HT), dopamine (DA), GABA (γ-aminobutyric acid) and probably acetycholine. Some investigators have suggested that second-messenger systems – such as adenylat cyclase, phosphotidylinositol, and calcium regulation – may also have relevance. Furthermore there are strong evidences for the involvement of neuroendocrine systems – such as the adrenal- and thyroid axis, and the regulation of growth hormone release. At last researchers have reported immunological abnormalities in patients with mood disorders. The dysregulation of the cortisol axis may modify the immune status; there may be abnormal hypothalamic regulation of the immune system (see KAPLAN et al. 1994, p.518 ff., KREAMER 1992 and GILBERT 1989 p.128 ff. for good reviews). However, all these changes on the psychobiological levels occurring after separation, which invokes a biphasic response sequence usually referring to as protest-despair, manifest in changed patterns of behaviour. Thus these changes can be accessed via observation. 4.1.8 The role of depression and suicide Helpful in understanding lovesickness is fact that the ending of a romantic relationship is closely associated with two serious disturbances: depression and suicide. In Gahleitner-Sengers study, 69 percent of the participants showed depressive annoyance (GAHLEITNER-SENGER 1992) after separation. In 1991, Means interviewed college students who had just been abandoned. That study showed that 40 percent of the students were clinically depressed (MEANS 1991). Heikkinen, Aro and Jouko published an article in 1993 in which they reviewed the literature on life events and social support in suicide. A recurring motive for suicide seems to be bereavement (HEIKKINEN et al. 1993). In most cases, as they report, depression would be a mediating factor between bereavement and suicide. Heikinnen and his colleagues promoted a systemic process model of suicide. - 13 ... suicide can be considered as a time-advancing process that is affected by complex biological, psychological, social, cultural and societal factors. Longterm risk factors can be outlined during the life course and within the suicide process both at the populational and at the individual level. Heikinnen et al. 1993, p.344 They argue further that adverse life events – e.g. loss – are risk factors which can trigger an outburst of suicidal intent. The counterpart are protective factors, e.g. strong social support systems, which operate against suicidal intent. During one’s life history, the equilibrium between risk and protective factors can vary. Thus lovesickness, along with bereavement and social loss, seems to be a high risk factor. This view is supported by two other recent studies. Hawton et al. investigated attempted suicides in Oxford University students. The concluded that The most common problems faced by the students at the time of their attempts were interpersonal, particularly concerning difficulties with partners.... Hawton et al. 1995, p.187. Within the ten highest ranked problems for all students ‘Break-up with partner’ ranked fifth (24 %, N=177). When problems were ranked by major areas of difficulty, ‘Interpersonal’ ranked first with 83 % of cases (HAWTON et al. 1995). BRENT et al. 1993 discovered in a case control study of 67 adolescent suicide victims and 67 matched controls that: In the year before death, suicide completers were more likely to have experienced: (1) interpersonal conflict with partners and with boy/girlfriends, (2) disruption of a romantic relationship, (3) legal or disciplinary problems. Brent et al. 1993, p.179 In the study’s overall frequency of stressful life events, interpersonal loss of boy/girlfriend reached 40% among the sample as against 20% in the control group. 4.1.9 Lovesickness and maladaptation 4.1.9.1 Is lovesickness a syndrome? There are very few ‘hard facts’ known about lovesickness. Neither well-founded physiological mechanisms, nor underlying intra-psychic processes have been discovered yet. Very different coping styles, depending on personality structure and sex, are used to overcome the loss. At any rate, psychological and phylogenetic ‘origins’ of lovesickness remain in the dark. In light of this, could lovesickness, given the current state of scattered knowledge, handled best as a syndrome? 4.1.9.2 Is lovesickness a disorder at all? Bereavement per se seems to suggest few analytical difficulties and is not viewed as a mental disorder. It is the ‘normal’ pattern of reaction after the loss of a beloved person. Similarly, a loss of (romantic) love will be succeeded by lovesickness. So the question that arises is whether lovesickness is a disorder or not. - 14 - In official diagnostic manuals for mental disorders (e.g. DSM III, American Psychiatric Association 1987), lovesickness is not listed explicitly. A feasible approach would seem to be to locate clinical symptoms of known disorders associated with bereavement, which are similar to those shown by people with lovesickness. In combination with results from depression and suicide research, lovesickness could then probably be integrated into the section ‘mood disorder’ of standard diagnostic manuals. As shown above, lovesickness seems to be an cross cultural phenomenon, and no process of natural selection ‘eliminated’ the ‘disorder’. This would suggest that lovesickness could have an adaptive value. I will conclude the theoretical considerations with a quote by Michael Liebowitz. At this point many of you must be asking yourself: ‘So someone gets depressed after a romantic breakup, or feels good if the lover with whom they’ve had a fight calls the next day. What makes this a psychiatric disorder? If it is, aren’t we all hysteroid dysphorics?’ Liebowitz 1983, p. 167 4.2 Methodological considerations 4.2.1 Compound approach to lovesickness Current data about human behaviour are mostly acquired through psychological studies. They are normally conducted with questionnaires and experiments. Studies with ‘behavioural real time field observation’ can hardly be found in the ‘scientific world of psychology’. As a consequence, these studies are often motivated by questions either about ‘emotions’ or about ‘cognition’, regardless of ‘real time behaviour’. The current study has tried to choose a compound approach to human behaviour which, however, focuses on a special aspect – lovesickness. This approach covers all three levels – emotion, cognition and behaviour – following the idea of the ‘unity of the human psyche’. The connection between ‘feeling’, ‘thinking’ and ‘acting’ has already been discussed by various scientist (see following reference in CIOMPI 1982; p.45, 46), Freud in his Entwurf einer Psychologie (FREUD 1895) and Traumdeutung (FREUD 1900) and Piaget in his Die Psychologie des Kindes (PIAGET & INHELDER 1966). The Swiss psychiatrist Luc Ciompi has combined Freud’s psychoanalytic views about emotions and affects with Piaget’s ‘genetische Epistomologie’ and formulated his Logik der Affekte (CIOMPI 1982). An important aspect of Ciompis ‘Affektlogik’ is that he embeds his theory in the framework of ‘systems theory’. The main point in this theory is a shift of perception, from watching isolated system features to looking at a system as a whole. The core of Systems theory was formulated by Ludwig Bertalanffy, an Austrian biologist (BERTALANFFY 1928 and 1950, see reference in CIOMPI 1982, p.17) and J.G. Miller who defined ‘system’ as a ‘set’ of elements which are connected to - 15 - each other, while the state of every element is determined by the state of all other elements (MILLER 1975, see reference in CIOMPI 1982, p.18). Ciompi states: Es scheint kein Zweifel mehr zu bestehen, daß es eine ‘AffektLogik’ gibt, das heißt, daß unsere psychische Wirklichkeit, unser erleben in jedem Moment sowohl affektive wie kognitive Elemente umfaßt, die unzertrennlich zusammengehören und sich auch gemeinsam strukturieren. Ciompi 1982, p. 90,91 From this point of view, lovesickness is then viewed as a manifestation of the human psyche, expressed through three cross-referring systems: emotion, cognition and behaviour. For purposes of simplification, lovesickness can be designated as a ‘behaviour’. If lovesickness is a behaviour, it can be studied in ‘real time’ with scientific methods. In this case, ethological methods are the appropriate tool. Ethology can be briefly defined as the application of orthodox methods to the problems of behaviour. Lorenz 1960a (see reference in Lehner 1996, p. 2) 4.2.2. Orthodox versus non-orthodox behavioural methodologies Methodologically, this study subscribes to Tinbergen’s four areas of study in ethology: Function, causation, ontogeny and evolution (TINBERGEN 1963). Traditionally ethology codes behaviour with systems of discrete categories. Behaviour is either described empirically or functionally. This process is known as ‘repertoire analysis’, leading to an ‘ethogramm’ with various more or less semantic descriptions of behaviour. This ‘orthodox’ position in the study of animal communication is based on the sign stimulus/releaser – fixed action pattern concept. The receiver decodes a distinct signal and then reacts. Contrary to Lorenz’s definition, however, the current study has used ‘non-orthodox’ methods to study behaviour. After many years of behavioural research and many attempts to establish a ‘human ethogramme’, the fixed action pattern concept (LORENZ 1965, TINBERGEN 1953) for studying communication processes turned out to be insufficient, due to the following reasons (see table 7). Table 7: Reasons for the insufficiency of the fixed action pattern concept (Grammer 1996). reason 1 2 3 4 5 6 7 The ‘meaning’ of signals is dependent upon too many parameters Signals show high inter- and intra-individual variations One signal can be substituted by an other Signals are used independently from context Nonverbal behaviour seems to be probabilistic Nonverbal behaviour is ‘culture constrained’ One and the same behaviour can be performed with varied and inconsistent ‘quality’ - 16 - A exemplary demonstration of this problem comes from Spencer: A man lifts his arm. One simple action may have many ‘causes’. Is he directing traffic or defending himself? Is he having a fit or is he dyskinetic? Our explanations will have philosophical implications. The more involuntary we regard the action as being, the more mechanistic will be our cause; the more voluntary the action appears, the more likely will we be to invoke intentions and purpose (and responsibility) in the subject. But how do we know which is the more relevant and how do we deal with blurred distinctions? Is the catatonic man who holds his arm in crucified pose acting intentionally or mechanistically? Is he acting at all? Spencer 1996 Thus much effort has gone into developing ‘non-orthodox methodologies’ which do not rely on ‘semantics’. In the current study, a methodology of that kind, called MED (Motion Energy Detection) has been used, which concentrates on the most genuine feature of any behaviour – motion. It will be discussed briefly , later in the section ‘methods’. A non-semantic approach to behavioural analysis acquires data from so called ‘low level’ shares of either visual or acoustic information. In vision these are: motion, contrast, colour and depth. It is assumed that these features transmit much more information for cognitive systems than previously supposed (see GRAMMER et al. 1996 for a detailed discussion). 4.2.3 Behavioural data about lovesickness There is no current behavioural data available on lovesickness. Instead, facts about behavioural changes accompanying mood disorders (e.g. depression) can be found. Most studies about the functionality of depression are based on neurology, more particularly on neuroanatomy and neurophysiology. These studies suggest that during depression the human brain is ‘dysfunctioning’, expressed through a reduced cerebral blood flow (CBF) in different anatomical areas (CUMMINGS 1993, FLINT et al.1993, GEORGE 1993 u.1997, ITO 1995, JARACZ 1996, KETTER 1997, KLEMM 1996, MAYBERG 1994, YAZICI 1992). However, only a small number of studies focus on behavioural aspects of depression. One basic assumption in the rather outdated field of psychology known as the ‘psychology of expression’ is that a change in mood alters behavioural expression, which can be observed (KIRCHHOFF 1965). This concept has been used by modern researchers to describe behavioural changes e.g. during depression or recovery from depression. Schelde et al. and Pedersen et al. observed patients with endogenous depression and recorded behavioural data using ‘repertoire analysis’ (142 different categories). They discovered that during remission patients showed more behaviour, increased visual contact, social contact, and more communicative intentions (SCHELDE et al. 1988, PEDERSEN et al. 1988). Fisch, Frey and Hirsbrunner studied 19 patients diagnosed as having suffered depression over a period of 9 months. They compared the patients’ movement - 17 - patterns performed at the onset of the therapy to them at the offset. The interview sessions were videotaped and transcribed with a behavioural coding system, called ‘Bernese System (BTSN)’. It includes a repertoire with 55 different behavioural dimensions, covering movements of the head, upper part of body, shoulders, upper arms, hands, thighs and feet over time. The data were subsumed into three parameters describing changes in any movement pattern (see table 8). Table 8: Parameters which describe changes in movement patterns according to Fisch et al. 1983. parameter Mobility Complexity Dynamics of activation 1 2 3 description How much time is spent in motion. How many body parts are moved together. How often movement patterns are induced and terminated. The authors demonstrated that patients in remission showed increased mobility, complexity and dynamics of activation, independently of the interviewer’s behaviour (FISCH et al. 1983). Thus patients showed not only ‘more’ behaviour; their ‘movement quality’ also changed, which reinforces the ‘non-semantic’ approach to behavioural analysis. Atzwanger and Schmitt inspected the relationship between depression and walking speed. They compared groups of subjects, classified according to Beck’s depression inventory (BDI) and found a negative correlation between Beck score and walking speed (ATZWANGER & SCHMITT 1996). Similar results were obtained by Sloman et al. They measured the ground force patterns of clinically depressed patients and showed that the push-off force was reduced. In an other study they showed that ‘lower mood individuals’ resemble clinically depressed individuals in behavioural performance (SLOMAN et al. 1982, 1987). Finally, all these findings imply therapeutic consequences - physical exercise (GREIST et al. 1978, 1979). Many clinical scientists today promote psychomotor monitoring as an appropriate methodology in psychopathological questions (GREDEN 1993, FLINT et al. 1993, KUNY & STASSEN 1993, LATASH & ANSON 1996). However, as previously mentioned, this study uses low level parameters for behavioural description of motion units (see detailed information later on in the section ‘methods’); see table 9. Table 9: Parameters for description of movement units, used in this study. parameter 1 2 3 4 description Emphasis Duration Speed Number The amplitude of a movement unit The length of a movement unit The average speed of a movement unit Total number of units over time - 18 - To conclude, the objective of this study was to develop a systematic approach to investigate lovesickness, previously a taboo of empirical science, which would integrate emotion, cognition and behaviour. (5) O B J E C T I V E S The objective of this study was to develop a systematic approach to investigate lovesickness. A major part of the study was devoted to exploring and describing lovesickness in different areas. Most of these questions (see 5.1) were answered within the ‘first level study’ (see 6.1). Hypotheses (see 5.2) covering the relation between ‘mate quality’, similarity, relationship parameters and depression were investigated within the ‘second level study’ (see 6.2). 5.1 Hypotheses - first Level 5.1.1 Basic Emotions (a) (b) Which basic emotions are involved in lovesickness? Hypothesis: Since lovesickness in this context is similar to the grief reaction, mostly grief and fear should be involved. Are there differences between the sexes (point a and b)? Hypothesis: No predictions. 5.1.2 Psychology (a) (b) (c) Which changes within the emotional status of the participants can be observed over time? Hypothesis: No predictions. What role does self-reported ‘emotional intimacy’ (closeness) between the partners play in relation to emotional status after abandonment and to duration of the relationship? Hypothesis I: No predictions, except depression (see c, Hypothesis III). Hypothesis II: The higher the degree of closeness between partners the longer the relationship lasted. What part does depression play in lovesickness? Hypothesis I: Subjects with lovesickness are in a depressionlike situation. Therefore, the more recently separation has occurred, the more depressed the subjects are. Hypothesis II: Does the duration of the relationships function as an intervening variable? The longer the relationship lasted, the more depressed the subjects are. Hypothesis III: Does ‘emotional intimacy’ have an effect on the score for depression? Was the higher the intimacy, the higher the score for depression? - 19 - (d) (e) How is suicide (suicidal ideation) related to lovesickness? Hypothesis I: Suicidal thoughts should play a major part in lovesickness. Are there differences between the sexes (point a, b, c and d)? Hypothesis: No prediction. 5.1.3 Behaviour 5.1.3.1 Nonverbal behaviour (a) How are changes in emotional status related to changes in nonverbal behaviour, especially to depression? Hypothesis: Quality features (emphasis, duration, speed and total number of movement units) of movement units decrease in amount with increasing depression. (b) Are there sex differences in quality features? Hypothesis: No predictions 5.1.3.2 Speech – Prosodic (a) How are changes in emotional status related to changes in prosodic, especially to depression? Hypothesis: Quality features (emphasis, duration, speed and total number of movement units) of prosodic units decrease in amount with increasing depression. (b) Are there sex differences in quality features? Hypothesis: No predictions 5.2 Hypotheses - second level 5.2.1 Similarity – Mate Quality (a) (b) (c) Are similarities correlated between (ex)mates? Hypothesis: Correlation coefficients between items differ in strength within pairs. Does similarity has an impact on the duration of the relationship? Hypothesis: The more similar the mates are, the longer the relationship lasted. Post hoc hypothesis: Does ‘mate quality’ play a part in the decision to leave the relationship? - 20 - (6) M E T H O D S The data were collected at the ‘Ludwig Boltzmann Institute for Urban Ethology’ c/o ‘Institute for Human Biology’ - University of Vienna. The study was primarily based on a semistructured interview. The experimental design is structured into a first and a second level study, where the first level study consists of three parts: the recording of the cognitive, the emotional and the behavioural parameters. Participants were asked for permission to use all material in research. 6.1 First level study 6.1.1 Definition of broken heart, or lovesickness. Person A is engaged with person B in an intimate relationship. Person A is being left by person B. After separation from person A, person B enters a state of cognitive, emotional and behavioural turbulence. This results in an unstable psychobiological state, which is called lovesickness. 6.1.2 Criteria for choosing subjects The study considered subjects only if: (a) the subject had been left by her or his partner in the relationship (b) the relationship had lasted more than 2 months (c) the separation had occurred sometime within 18 months of the interview 6.1.3 Description of subjects The sample consisted of 22 subjects (11 female, 11 male), ranging in age from 18 to 30 years. The average age for the females was 22.4 years (SD= 2.2) and that for males 24.6 years (SD= 3.0). 6.1.4 Relationship parameters The duration of the relationships ranged from 2 to 96 months, the average length for the female was 27.7 months (SD= 27) and for the males 28.9 months (SD=26.1). The time elapsed since separation ranged from 0.19 to 14 months. The average length of time for the females was 3.3 months (SD= 2.9) and for the males 3.7 months (SD= 3.7). 6.1.5 Acquisition of cognitive parameters All subjects underwent a semistructured interview (approx. 60 min.), consisting of questions with predefined answering possibilities and questions with narrative answering (see appendix -A-). - 21 - 6.1.6 Acquisition of emotional parameters The emotional status of the subjects was recorded with a clinical selfreport test, the ‘Eigenschaftswörterliste-EWL’ according to JANKE & DEBUS 1978. The answering scheme was changed from the original ‘ no-yes ‘ to a four point ordinal scale, in order to obtain more differentiated results (see appendix -B-). The evaluation of the test was not influenced by these modifications. Following the statistical instructions, different indices were calculated: activation, concentration, deactivation, sleepiness, dizziness, extroversion, introversion, self-confidence, elation, excitement, sensibility, anger, fearfulness, depression, and dreaminess. 6.1.7 Acquisition of ‘emotional intimacy’(closeness) between the partners. Participants were told to show their view of closeness to their ex-partners retrospectively for the ‘high times’ of the relationship. The subjects used two circles to depict the level of closeness (see figure1). Partner Subject Figure. 1: Acquisition of intimacy between partners. The amount of overlap was calculated and expressed as percentage from full circle area. 6.1.8 Involvement of Emotions The subjects were asked to rate (on a 7-point scale) a selection of different emotions relevant for the description of lovesickness (see appendix -C-). The selection of the emotions were based on EKMAN & FRIESEN 1978; see table 10. Table 10: Emotions used for description of lovesickness by the subjects. emotions 1 2 3 4 5 6 7 8 9 fear surprise rage disgust joy panic anger grief pain - 22 - 6.1.9 Acquisition of behavioural parameters Figure 2: The setting of interviewer, subject and position of hidden video camera. 6.1.9.1 The setting The consulting room, arrangement of seating and the camera location were identical for each interview session. The subjects were unobtrusively videotaped during the interview situation (see figure 2). The videotapes were analysed with ‘Automatic Movie Analysis (AMA)’, done by a computer in order to assess movement quality (Motion Energy Detection, MED). Outcomes of behavioural data analyses were related to questionnaire data (relationship, cognitive and emotional parameters). 6.1.9.2 Automatic Movie Analysis (AMA) The video sequence (approx. 30 sec.) analysed was that subsequent to the following question in the interview: ‘What were the reasons for the separation?’ In the following, the steps of the AMA procedure will be explained in brief (for details see GRAMMER et al. 1996). 1. Digitising the clips Every 30 sec. video clip was digitised with 25 frames/s (images and sound) using a greyscale of 256 values (0=white, 256=black). For further calculations 3 ROIs were used (Regions Of Interest: upper body, lower body and whole body). AMA software allows one to choose and fix different ROIs before starting the analysis. Z 2. Calculating difference pictures (Motion Energy Detection) By subtracting frame by frame, the absolute change of every pixels greyvalue can be traced over time. A difference picture consists of many such greyvalues, ranging from zero (no change) to 256 (maximum change). The fluctuating greyvalues represent the amount of change occurring from frame to frame. In this way, changes in the object, contrasted against background, can be detected by the software. 3. Reducing noise Normally white noise is produced randomly by inhomogeneous tape quality, limitations to the camera resolution, errors through frame capture technique, or slight changes in lightening conditions. Consequently, each pixel represents the median greyvalue of the nine pixels surrounding it (median filtering technique). Thus no ‘erratic pixels’ are taken into account for further calculations. - 23 - 4. Calculating series of greydensity The mean greyvalue of all pixels for each ROI was calculated. This 0,133 represents the total amount of a person’s movement between two 0,030 0,042 related frames. Plotted against time or frames, one obtains a series of greydensities, each representing a difference picture. 5. Transformation of greydensities To diminish the problem of different viewing angles of the person and different greydensity base lines, greydensities were transformed to zscores. 6. Smoothing the data stream In order to avoid small and short (single frame) changes of greydensity, the signal was smoothed with a 5-point moving average. 7. Eliminating flashes Flashes arise due to poor tape quality and electrical instability of the recording equipment. They are recognised automatically and removed after visual verification. The gap was filled by the average density of F-1 and F+1. 8. Thresholding and segmenting For quantitative analysis, the continuous stream of greydensities is segmented into units of movement. An movement unit is defined as the threshold surplus from one threshold crossing to the following one. Therefore an optimal-thresholding technique was used. 9. Calculation of variables (a) Nonverbal behaviour The quality of movement was described by 4 variables (see figure 3). All variables are related to single movement units. Emphasis: the amplitude of a movement unit’s flexion (unit size) Duration: the length of a movement unit over time from one threshold crossing to the following one. Speed: the average speed of the moving area under the curve per unit of time (duration divided through duration). Number: total number of units over time. (b) Speech prosodic The same procedure was used for speech data to describe prosodic features over time (envelope). - 24 - greyvalues changes 1,200 treshold 1 to 7 = number of units 1,000 4 0,800 6 emphasis 3 0,600 unit 0,400 1 0,200 speed 2 duration 5 0,000 1 10 19 28 37 46 55 64 73 82 91 100 frames Figure. 3: AMA output and description of variables. Figure 3 shows a graphically visualised output from AMA. Changes of greyvalues are plotted against time (=frames). Further descriptions of the variables emphasis, duration, speed and number of units are shown. 6.2 Second level Study - rating study of faces. 6.2.1 Description of subjects (raters) The sample consisted of 33 raters (15 female, 18 male) ranging in age from 18 to 31 years. The average age for the females was 25.1 years (SD= 2.9) and that for males 21.6 years (SD= 2.3). 6.2.2 Rating of Faces 6.2.2.1 The setting Photographs from the participants of the first level study were taken with a videostill camera. In addition, if possible the subjects made photos of their ex-partners available. Finally, the set consisted of 42 photographs, that is, 21 pairs of faces. All photos were digitised and converted to greyscale pictures. These pictures were fed into a computer programme (‘Facetest’), in order to perform the rating study. The results obtained were related to questionnaire data (relationship, cognitive and emotional parameters). - 25 - 6.2.2.2 ‘Facetest’ Facetest is a computer programme for performing rating studies. Sets of pictures can be loaded to rate with a set of either unipolar or bipolar adjectives. In this case 29 bipolar adjectives (see appendix -D-) were used, a selection from a larger set developed by HENSS 1992. The scale between the two poles covered a 7-point range. Pictures and items were both presented randomly on the screen. The rating was done by clicking on the 7-point scale via computer-mouse. Every participant rated all 42 pictures. 6.3 Statistical analysis was done by computer with SPSS 7.0. - 26 - (7) R E S U L T S Results are presented in same order as hypotheses before. 7.1 Hypotheses – first level 7.1.1 Basic Emotions (a) Which basic emotions are involved in lovesickness? Hypothesis: Since lovesickness in this context is similar to the grief reaction, mostly grief and fear should be involved. joy 1,00 / 2,4% disgust 1,00 / 2,4% rage 4,50 / 10,8% surprise 6,00 / 14,5% anger 5,00 / 12,0% fear 5,00 / 12,0% panic 5,00 / 12,0% grief 7,00 / 16,9% pain 7,00 / 16,9% Figure 4: Pie chart showing involvement of all emotions in lovesickness. The two most prominent and the two least prominent slices are exploded. Values show median/percentage as summary function for different variables. The results suggest that grief and pain rather than grief and fear are involved (see figure 4). Joy and disgust seem to play either a marginal or no role in lovesickness. To test these assumptions a Binomial Test was performed. Answers were recorded into two groups. Group 1 contains all cases with rating values ≤ 4, group 2 all cases with values > 4. The test proportion was assumed to be 0,5. Medians for grief and pain are at 7 (=maximum value). Both emotions differ significantly from random distribution (p=0.000). Joy and disgust can be significantly excluded (p=0.000). All other emotions (anger, fear, panic, surprise and rage) do not differ from random distribution between group 1 and 2. Table 11 shows the results of the Binomial Test. - 27 - Table 11: Results of the binomial test show which emotions are definitely involved in lovesickness. The test proportion was assumed to be 0,5. Group 1 contains all cases with a rating ≤ 4 (supposed as ‘not relevant’ for lovesickness), whereas group 2 contains all cases with a rating > 4 (supposed as ‘relevant’ for lovesickness).

Therefore Spearman’s correlation was conducted between the 15 subscales of the EWL (activation, concentration, deactivation, sleepiness, dizziness, extroversion, introversion, self-confidence, elation, excitement, sensibility, anger, fearfulness, depression, dreaminess) and the time elapsed since separation (see table. 12).

Hypothesis I: No predictions for emotional status, except depression (see c, Hypothesis III). Hypothesis II: The higher the degree of closeness between partners the longer the relationship lasted. No significant Spearman’s correlation could be found between 15 EWL-subscales and emotional intimacy, not even for depression. No significant Spearman’s correlation between closeness and duration of the relationship was found. An additional Spearman’s correlation was performed for closeness and time elapsed since abandonment. A non-significant trend was discovered, showing the longer the time elapsed since separation, the higher closeness was reported to be (r=0.38, p=0.07, N=22). (c) What part does depression play in lovesickness? Hypothesis I: Subjects with lovesickness are in a depression-like situation. Therefore, the more recently separation has occurred, the more depressed the subjects are. Hypothesis II: Does the duration of the relationships function as an intervening variable? The longer the relationship lasted, the more depressed the subjects are. Hypothesis III: Does emotional intimacy have an effect on the score for depression? Was the higher the intimacy, the higher the score for depression? A significant correlation (Spearman) between the score for depression and time elapsed since separation could be discovered (r=-0.438, p=0.042). The shorter the time lag, the higher the score for depression. No significant correlation could be found for duration of relationship and depression score. Only a non-significant trend for depression and closeness could be discovered (r=0.32, p=0.13, N=22). - 30 - (d) Are there differences between the sexes concerning point ‘a’ and/or ‘b’ and/or ‘c’? After conducting a ‘Kolmogorov Smirnov two sample test’, neither in point ‘a’ nor in ‘b’ and ‘c’ were significant differences between the sexes discovered. (e) How is Suicide (suicidal ideation) related to lovesickness. Hypothesis I: Suicidal thoughts should play a major part in lovesickness. Table 14: Suicidal ideation and related percentages. percentage Did suicidal thoughts come up immediately after the separation? no yes 54,5 % 45,5 % Table 14 shows that 45.5 % answered the question ‘Did suicidal thoughts come up immediately after the separation?’ with ‘yes’, 54.5 % with ‘no’. After performing a ‘Kolmogorov Smirnov two sample test’, no significant differences between the sexes were discovered. 7.1.3 Behaviour The selection of the EWL subscales, correlated with behavioural data, were based on the results in point 7.1.2 (a) (see table 14 and 15) and on the interest in the impact of depression on behavioural changes. Besides depression only those subscales were taken into consideration which correlated with time elapsed since abandonment (see table 15). The subcale introversion was the only one of the subscales that showed no interdependencies with any other subscales, apart from extroversion (see table 12). 7.1.3.1. Depression 7.1.3.1.1 Nonverbal behaviour (a) How are changes in emotional status related to changes in nonverbal behaviour, especially to depression? Quality features (emphasis, duration, speed and total number) of movement units decrease in amount with increasing depression. - 31 - 7.1.3.1.1.1 Single movement unit analysis Values for quality features were calculated for every single movement unit.

See table 15 for correlation coefficients. Firstly, Spearman’s correlation between quality features and depression scores were conducted (see table 15). Significant results concerning 3 features could be found. Emphasis, speed and duration were correlated negatively with depression score. No correlation could be found for number of movements and depression score. Figure 5 shows the corresponding multiple scatter plot. In none of the variables (emphasis, speed and duration) could significant differences between the sexes be discovered (‘Kolmogorov Smirnov two sample test’). - 32 - Controlling the effect of ‘time passed since separation (time)’ on depression score Pearson’s correlation was performed. Therefore quality features were correlated with ‘time’ (see table 16). Only emphasis and speed yielded a significant correlation.

For additional analysis, values of quality features were calculated over the whole sampling period.

No significant correlation could be discovered either between quality features and depression score or between quality features and ‘time’. - 33 - 7.1.3.1.2 Prosodic of speech (b) Quality features (emphasis, duration, speed and total number) of speech units decrease in amount with increasing depression. 7.1.3.1.2.1 Single speech unit analysis Here, too, Spearman’s correlation between the 4 quality features of single speech units and depression scores was performed. In this case only duration of units yielded a significant correlation (r= -0.622, p=0.002). Quality features were also, as previously, correlated with ‘time’.

No significant differences between the sexes were discovered in any calculations. 7.1.3.2 Introversion Neither single unit analysis nor integration analysis of behaviour and speech data in relation to introversion scores showed any significant results. In this case changes of introversion scores over time were not expressed through changes in movement quality. - 34 - 7.2 Hypotheses – second level Before conducting any statistics, additional calculations were applied to results from the rating test (‘face test’). 7.2.1 Index for difference within a pair (Id). I) For all 29 rating items (RI) a sex specific mean was calculated. II) For every item, and for both mates separately, the difference from its sex specific mean was calculated. III) For each pair of (ex)mates, a subtotal of differences was calculated for each item. IV) For each pair, all item subtotals were subsumed under one single value, the index for difference. 7.2.2 Controlling for ‘smiling faces’ The sample of faces (n=40) used for this rating test was very heterogeneous. One half of the sample (participants of the study) contained rather neutral photo portraits, which had been taken by the researcher. The other half consisted of photo portraits brought by the participants, showing the (ex)mates in very different situations and moods, often with smiling faces. It is known that smiling can function as an intervening variable that influences rating processes. For example, smiling faces are judged as more attractive than not smiling faces. A Mann-Whitney-Test was performed to control whether in one half of the photographs there are more ‘smiling faces’ than in the other. The test showed no significant results (n=40, U=146.5, p=0.154); ‘smiling faces’ are distributed randomly between the two halves. 7.2.3 The hypotheses (a) Are there similarities between the (ex)mates? Hypothesis: Correlation coefficients between rating items within the pairs differ in strengths. After performing Spearman’s correlation, none of the rating items were significantly correlated (within pairs). (b) Does similarity have an impact on the duration of the relationship? Hypothesis: The higher the similarity (Id) between mates is, the longer the relationship lasted. No significant Pearson’s correlation between Id and duration could be discovered. - 35 - (c) Does ‘mate quality’ play a part in the decision to leave the relationship (post hoc)? To test this hypothesis, a key variable, in sociobiological terms, for mate quality was used – attractiveness. The sample was divided into two sub-groups, in more attractive and less attractive subjects. Those two groups were tested against ‘leavers’ and ‘leavees’ (the left ones) in a chi-square test, first for both sexes and then for each sex separately. All three chi-square test were not significant, although an interesting trend was observed (Table 18 and Figure 7). Table 18: Leavers are compared with ‘leavees’ according to attractiveness. Values represent total percent. Figure 7 shows corresponding graph for all cases. leavees leavers (left ones) more attractive all cases less attractive more attractive males less attractive more attractive females less attractive 28,6 % 19,0 % 25,0 % 20,0 % 31,8 % 18,2 % 21,4 % 31,0 % 15,0 % 40,0 % 27,3 % 22,7 % percentage of cases - total percent 50 40 all cases p=0.217 30 20 10 0 leavers leavees (left ones) more attractive 28,6 21,4 less attractive 19 31 Figure 7: Comparison of attractiveness between leavers and leavees. Differences are not significant (chi-square-test, p=0.217), but a trend was discovered. The leavers show a higher percentage of more attractive subjects than the leavees. Looking at the results for ‘all cases’ (Table 18) the trend shows that the leavers represent a higher percentage (28,6 %) of more attractive subjects than the leavees (21,4 %). More evidence shows the results for ‘males’ (leavers 25 %, leavees 15%). The results for the ‘females’ show a slight trend in the same direction but less strong than that in the ‘males’. - 36 - (8) S U M M A R Y - D I S C U S S I O N - C O N C L U S I O N S 8.1 What is new in this study? (1) Systematic study of ‘Lovesickness’ (2) Multi-level approach (behaviour – emotion – cognition) (3) Alternative behavioural methodology (4) Introducing ‘Broken Heart Syndrome BHS’ (5) Adaptive value of BHS (6) BHS and therapy 8.1.1 Systematic study This study has attempted to employ a systematic approach to the ‘broken heart’ phenomenon (in German ‘Liebeskummer’). The approach is systematic in the sense of subject choice (restrictions to age, duration of relationship and time passed since abandonment) and of the definition of the phenomenon investigated. 8.1.2 Multi-level approach The scientific approach adopted covered all three traditional areas of behavioural research (cognition, emotion and behaviour). A wide range of starting points was established to grab facts about a vague psychological phenomenon. 8.1.3 Alternative behavioural methodology A non-semantic approach to behavioural analysis was chosen which yielded information about an important state of the human psyche. For the analysis we chose a basic feature of human behaviour, motion. Specifically, we monitored the changes of motion energy via computer (AMA and MED). 8.1.4 Introducing the Broken Heart Syndrome (BHS) According to Psychrembels definition of syndrome Syn|drom (gr. συνδροµος mitlaufend, begleitend) n: (engl.) syndrome; Symptomkomplex; Gruppe von Krankheitsanzeichen, die für ein best. Krankheitsbild mit meist uneinheitlicher od. unbekannter Ätiologie bzw. Pathogenese charakteristisch sind. [...group of symptoms which are characteristic for a certain clinical picture with irregular or unknown aetiology res. pathogenesis.] Psychrembel 257th edition 1994 - 37 - We would classify lovesickness as a syndrome, the Broken Heart Syndrome (BHS), which best describes the situation of the bereaved after the loss of a romantic relationship. This syndrome includes elements of the ‘grief process’, in particular the ‘major depression episode’, and is accompanied by suicidal thoughts and behavioural changes, specifically behaviour becomes less expressive. 8.1.5 Adaptive value of the BHS 8.1.5.1 Emotions as communicators In psychological terms which employ a semantic definition, emotions are defined as a ‘fundamental motivating system’; they are those ‘processes of personality which attach sense and meaning to the human existence’ (IZARD 1994 p.63). Biological theories of communication, which make use of a pragmatic definition, argue that emotions, because they are trigger signals, have primarily a communicative function. A major process of any communicative act is the manipulation of the other (DAWKINS & KREBS 1978). The predisposition to this is grounded in the fact that the display and interpretation of basic emotions are universal to all humans (GRAMMER 1993, p.103 and reference therein EKMAN 1984) and that emotions can have a manipulative intent. Thus if subject A displays an emotion to subject B, A tries to manipulate subject B’s actions according to A’s intentions. The display of an emotion lets the sender switch into a state more easily decipherable by the receiver. Therefore, the sender becomes more assessable for the receiver. The sender signals being ‘reliable’, in the sense of being readable. This readability should be a major criteria for choosing a social partner for any further, reciprocal social interactions, for example, cooperation. Emotions can only work as ‘manipulators’ if they channel communication processes in this way. Emotions thus have an adaptive value. 8.1.5.2 Grief and Bereavement So-called ‘negative’ emotional complexes like grief are accompanied by shame and guilt. For the most part, they are designated as ‘senseless’ emotions which should be avoided. In the therapeutic situation it is very difficult to motivate the clients and to sensitise them for the ‘positive powers’ of their negative stance. In the literature the ‘function’ of grief and related emotions have been extensively reported. These are mostly seen as a coping strategy: individual adaptation processes to replace the lost object (IZARD 1994, see reference therein BOWLBY 1960, 1961, 1963). In a broader sense, Averil speculated about the adaptive value of grief. He stated that: Grief is a biological reaction the evolutionary function of which is to ensure group cohesiveness in species where a social form of existence is necessary for survival. This is accomplished by making separation from the group, or from specific members of the group, an extremely stressful event both psychologically and physiologically. Averil 1968, p. 729 As previously mentioned, any of the existing emotions can serve the purpose of communication. Thus grief, apart from effecting individual adjustment to loss, also - 38 - functions as a communicative sign. It signals the readability and reliability of a person. In addition, it can elicit empathy and help from others. In this sense, grief would be seen as adaptive, too. 8.1.5.3 Depression Many theories suggest that different forms of ‘depression’ are evolutionarily adaptive. BISCHOF 1993 (pp. 33-57) speaks of depression as a ‘reassurance strategy’ via generation of a ‘super stimuli’ that evokes parental behaviour. AUBERT 1993 (pp.57-65) discusses the functionality of depression in relation to rank theory. He talks about the stabilising effect that the promotion of appeasement behaviour has for the social group. STEVENS & PRICE 1996 (pp. 57-81) discuss depression in a similar context. They write that ‘[t]he reason why depression is adaptive, is precisely because it promotes adjustment to attachment loss and loss of rank both at the same time’. 8.1.5.4 Functionality of BHS If one recognises that emotions in general (positive and negative) and in particular the display of these emotions, and that even affective disorders like depression have an adaptive value; and if BHS is a ‘special case of bereavement’ or grief reaction, complicated by a major depression episode, then we can conclude that BHS has an adaptive value (ontogenetic and phylogenetic) as well. Thus BHS and it’s related depression could be a strategy for the re-adjustment of ones self-image and in a more biological sense for the re-evaluation of ones ‘mate value’. 8.1.6 BHS and therapy Nevertheless, BHS can indicate a therapeutic intervention if it turns maladaptive for the individual. This aspect of any case of BHS should not be minimised. Maladaptation can be caused by, for example, a weak or hostile social network, or by additional psychic disorders of the subjects. A general problem seems to be that in comparison to traditional cultures there are no social ‘bereavement rituals’ that the ‘bereaved of today’ can go through. Instead, the bereaved often seeks refuge in isolation. 8.2. Discussion of the results in depth 8.2.1 Basic emotions The results suggested grief and pain as the emotions which predominate in lovesickness. The fact that anger, fear, panic and rage do not differ from random distribution between ‘relevant for lovesickness’ and ‘not relevant for lovesickness’ can be explained as resulting from an ‘I’m not sure’ answer by the participants. This is evident for these emotions because their medians were between 4.5 and 5.0 on the 7 point scale. No statistical difference from random distribution could be found for - 39 - ‘surprise’ either, but 64% of all cases are found in the group ‘relevant for lovesickness’. In this case it can be assumed that most of the participants were surprised by the decision of their (ex)partners to leave the relationship. So is there a ‘digitaloverwhelming-effect’? Yes, if one understands digital in the sense that the decision to separate is not drawn out over a longer period of time, but is a very spontaneous one. The ‘leavees’ (the abandoned), not having any time to adjust, are overwhelmed by it. Another explanation could be the ‘disbelief-effect’ (similar to the denial phase in the bereavement process, BOWLBY 1994), an outcome of constantly neglecting smouldering conflicts within the relationship (HATFIELD & RAPSON 1993, p.326; see reference therein: RUSBULT 1987). The disbelief in separation is then experienced as surprise through the ‘leavee’. Over all, lovesickness is best represented as a ‘cocktail’ with different portions of grief, pain, anger, fear, panic, rage and surprise. 8.2.2 Psychology The instant emotional state of the participants was recorded and the subscales of the psychological test (EWL) were correlated with time elapsed since abandonment. The results showed that ‘depression’ and ‘introversion’ decrease with time, while ‘extroversion’, ‘concentration’, ‘self-confidence’ and ‘elation’ increase with time. In short, negative emotions are vanishing and positive emotions, in particular motivation comes back. 8.2.3 Emotional Intimacy No significant relationship between emotional status in general after abandonment and the reported level of intimacy could be established. Neither could a significant relationship between the duration of the relationship and the reported level of intimacy be found. In addition, emotional intimacy was correlated with time elapsed since separation (not included in results). A non-significant trend was discovered (r=0.38, p=0.074, n=22). This result seems to be paradoxical, but it could force the methodological conclusion that romance rather than emotional intimacy was being measured. The longer the period of time elapsed since abandonment, the brighter the memories of the relationship become (see HATFIELD & RAPSON 1993, p.418). 8.2.4 Depression Clinically, the subjects’ emotional situation with lovesickness is very similar to the ‘Major Depressive Episode’ described in the DSM III. The DSM III reports that: Uncomplicated bereavement is distinguished from a Major Depressive Episode and is not considered a mental disorder even when associated with the full depressive syndrome. However, morbid preoccupation with worthlessness, suicidal ideation, marked functional impairment or psychomotorical retardation, or prolonged duration suggests that bereavement is complicated by a Major Depressive Episode. DSM III 1987, p.222 - 40 - The Textbook of Psychiatry (HALES et al. 1994, p.489-490), 2nd Edition also describes bereavement as an uncomplicated process, but concedes that it can turn into a ‘complicated mode’. They put ‘uncomplicated Bereavement’ into the category of ‘Disorders of Mood Yet Not Mood Disorders’, which only can be separated by differential diagnosis. Contradictory lovesickness seems to be a case of ‘complicated bereavement’ from the beginning on. However, we relied on the current suggestion that lovesickness is associated with depression, so it was considered to be a ‘continuous phenomenon’. This means that participants were labelled to be ‘more or less’ depressed, rather than ‘depressed’ versus ‘not depressed’ (see discussion in GILBERT 1992). We believe that this approach would be more suitable for looking at lovesickness, because it shows changes in emotional status (actually depression) more clearly and differentially. As predicted, subjects with lovesickness are in a depression-like situation, and scores for depression decreased over time. The shorter the period of time elapsed since abandonment, the higher the depression scores are. The second assumption, namely, that the duration of a relationship functions as an intervening variable, could not be proved. The third hypothesis, that emotional intimacy controls for depression, could not be proved statistically either. Only a non-significant trend towards this assumption could be reported. 8.2.5 Suicide In the case of suicidal thoughts only descriptive statistics were used. Nevertheless, none of the participants told about suicide attempts, a considerable percentage (45,5%) reported having had suicidal thoughts after abandonment. During the interview all subjects spoke of being ‘down in the dumps’ or having felt a complete emptiness; in short, they were stunned by the loss. This percentage corroborates other recent findings (GAHLEITNER-SENGER 1992). The first phase after the loss seems to be very similar to the initial phase of the bereavement or grief process (BOWLBY 1994, p.81ff; GAHLEITNER-SENGER 1992). In this phase the ‘emotional system’ undergoes a severe destabilisation, precipitated by the event. Suicidal thoughts in this phase must be taken seriously. Whether homeostasis is regained or not will depend on various environmental constraints (inputs from inand outside). In most cases, suicidal thoughts can be buffered by the system and they do not turn into suicide attempts. In short, and from a psychological point of view, lovesickness seems to be a special case of bereavement, complicated by a major depressive episode. If symptoms are sufficiently severe, people should undergo a therapeutic intervention. In this sample, only one of the participants had consulted a psychologist. Thus, for the most part time was the great healer. 8.2.6 Behaviour One of the objectives of this study was to integrate behavioural aspects into the ‘psychological’ phenomenon of lovesickness. The assumptions underlying this objective followed the framework of Ciompi’s ‘Affektlogik’. Another aim of this study was to reapply the ‘non-semantic approach’ (see GRAMMER et al. 1996 for first introduction) rather than a repertoire analysis to - 41 - nonverbal behaviour. This was based on computerised analysis of videotapes (Automatic Movie Analysis, AMA) and the description of movement quality and quantity (Motion Energy Detection, MED). Simple physical parameters were used to describe movements (number of units per time, emphasis, speed and duration). 8.2.6.1 Nonverbal behaviour Depression was picked out as a very prominent indicator for monitoring changes in the emotional status of the participants over time. In a nutshell, higher scores of depression were expressed through reduced motion energy rather than reduced motion quantity (movements were less emphatic, shorter and slower). So far, the results of this study are comparable with existing data (FISCH et al.1983, PEDERSEN et al. 1988). Deviating from these other studies is the result that participants do not show any significant changes in movement quantity. Participants with lower scores for depression showed no difference in movements per time compared to subjects with higher depression scores. Both former studies reported that the more subjects were depressed or the smaller the recovery from depression was, the less behaviour was shown: Upon recovery, patients spent more time in motion, displayed a more complex pattern of movement, and initiated and terminated movement activity more rapidly than when they were depressed. Fisch et al. 1983, p.316 In other words, depression seems to be characterised by general inactivity and restricted social interaction. Pedersen et al. 1988, p.325 According to current theory, psychiatric patient [in case of depression] tend to show a reduced motor activity. Fisch et al. 1983, p.308 Additional computations showed (in contradiction to GRAMMER et al. 1996) that no physical interrelation between movements per time, size (emphasis), duration and speed could be found. Therefore, movements per time are considered to be a ‘real variable’. Instead, a strong correlation between movements per time and total time spent in motion per time (r=0.89, p=0.000, N=22) was found, showing that subjects who make more movements spend more time in motion. This study thus suggests that in the case of depression people behave ‘differently’. The rate of behaviour (movement) is neither decreased nor increased, it remains unchanged. Thus depression is being expressed through a changed (decreased) movement quality or motion energy. If the movement flow was analysed as a whole, both effects (depression scores and ‘time’) on ‘quality features’ vanished. AMA and MED work with ‘low level processing algorithms’ to obtain information from changes in motion patterns. These basic processes are very similar to processes of visual perception as used by the human brain, which are well - 42 - reported in the literature (CARNEY et al. 1987, DEYOE & VAN ESSEN 1988, LIVINGSTONE & HUBEL 1988, VAN ESSEN & GALLANT 1994). Therefore, for AMA and MED single unit analysis of movements seems to be more appropriate than the analysis of the whole movement flow. The results would again suggest that our cognitive system can extract information about movement qualities, in particular, ‘behaviour’ in general, through low-level processing (see GRAMMER et al. 1996 for results). The conclusion would be that quality of movement provides an important information carrier. 8.2.6.2 Prosodics of speech Speech analysis, in particular assessing quality features, was conducted with AMA/MED as well. Both single units and flow of speech were analysed. While analysis of nonverbal behaviour showed consistent results when analysing single units of movement, speech tended to be treated best as a flow of speech (envelope). Performing correlations with quality features yielded another difference in the analysis of motion, namely, that in cases of speech, ‘time elapsed since abandonment’, rather than actual scores of depression, brought significant results. In short, speech flow became more emphatic, expressive and faster, the longer the time elapsed since separation. 8.2.7 Second level hypothesis In this second block, the hypothesis based on sociobiological theory concerning criteria of mate choice were tested. 8.2.7.1 The impact of similarity Surprisingly not a single significant correlation between any of the rating items (n=29) within the pairs was found. Nor could any relevant impact of similarity between the mates on the duration of the relationship be discovered. According to positive assortative mating strategy, mates are similar in different parameters, like physiognomy, age, social status, religion, social behaviour, attractiveness etc. In a vast number of studies (see GRAMMER 1993 and references therein) these ‘correlations between mates’ were found. In this study, none of these assumptions could be proved; on the contrary, all relationships in this sample had broken up. Thus this ‘negative result’ would corroborate indirectly positive assortative mating strategy. The fact that there is no differentiated effect of similarity on the duration of a relationship leads to the conclusion that there are early phase decisions as to whether a ‘young’ relationship is to be terminated or not. Thus the decision on whether or not to leave a relationship at an early stage is attributable to a base level of similarity between partners before the relationship begins, rather than in a growing adaptability in the relationship itself (CRADOCK 1991), which guarantees prolongation, stability and satisfaction in an already established relationship. 8.2.7.2 ‘Mate quality’ The post hoc hypothesis stated that mate quality played a role in the decision to leave the relationship. If assortative mating occurs and similarity is the reason for it, then a mismatch of such similarities would result in a break up between mates. In this view, - 43 - the mate with the higher ‘mate quality’ should be the one to leave the relationship. To test this, attractiveness was examined as a specific factor; the results suggested a trend towards confirmation of this assumption. In both sexes, those who were more attractive, i.e., those who represented higher ‘mate quality’ in sociobiological terms, abandoned the relationship. (9) R E F E R E N C E S Ainsworth M. D.
